Centromeres serve the same basic purpose in almost all living organisms. These regions of DNA ensure that chromosomes are properly separated during cell division. Despite this common role, the structure of centromeres varies widely. Some organisms have long stretches of repetitive DNA, but yeast use much smaller and simpler versions known as “point” centromeres. This amazing diversity, combined with the fact that centromeres evolve rapidly, has puzzled scientists for decades. A research team led by Andrea Musacchio, director of the Max Planck Institute for Molecular Physiology in Dortmund, along with Jeff Boeke of New York University’s Grossmann School of Medicine,…

Mayo Clinic researchers have identified a drug and supplement combination therapy that can reduce the negative effects of senescent cells, also known as “zombie cells,” in diabetic kidney disease. in e-biomedicinePublished in The Lancet, the research team reported that a combination of the cancer drug dasatanib and a natural substance known as quercetin reduced inflammation and increased protective factors in the kidneys. Diabetic kidney disease affects more than 12 million people in the United States and is the leading cause of kidney failure. New treatments can slow the loss of kidney function, but there is currently no cure. Our…

A simple five-minute test to address significant delays in endometriosis diagnosis and treatment has been developed by researchers at the University of Queensland. The Simplifying Factor for Adolescent Endometriosis (SAFE) score uses a questionnaire to identify at-risk patients and expedite referral to a specialist for further investigation. Professor Gita Mishra AO, director of the UQ Australian Women’s and Girls’ Health Research Center, said the test could avoid years of waiting for a diagnosis. This test uses six questions to detect girls or young women who are at risk for endometriosis and need further evaluation. ” Geeta Mishra AO,…

Evolution is nature’s way of designing biological systems. Many variations of DNA, RNA, and proteins occur within cells, and natural selection favors the organisms that function most effectively. Humans began using this process a long time ago. Early farmers influenced evolution by choosing which crops and livestock to reproduce, ensuring that the most productive plants and animals inherited their traits. Today, scientists apply similar principles in the laboratory through a technique known as directed evolution. Researchers use it to improve proteins such as enzymes and antibodies that play important roles in medicine, industrial manufacturing, and even everyday products such as…

Advice for staying healthy often focuses on regular exercise and limiting fatty foods. Physical activity helps lose excess weight, build muscles and strengthen the heart. It also improves the body’s ability to absorb oxygen and produce energy. It is considered one of the most reliable indicators of long-term health and longevity. However, people with high blood sugar levels often miss out on some of these benefits of exercise, especially the increased efficiency of the body’s use of oxygen. Elevated blood sugar levels increase your risk of heart and kidney disease. It can also interfere with your muscles’ ability to increase…

ODAKA, Japan (AP) — 15 years later 2011 nuclear disastera color-coded radiation map is posted on the wall of Futabaya Ryokan, a family-run inn run by Tomoko Kobayashi in her almost remote hometown in northeastern Fukushima. Kobayashi conducted her own radiation study before reopening the inn in 2016. Now, Kobayashi and other monitors are sharing radiation data as part of an effort to rebuild this once-bustling textile town.As Kobayashi passes by the kindergarten he attended as a child on his way to the Radiation Monitoring Institute, he talks about the town before the earthquake. Since the nuclear accident, there have…

New research published in nature communications revealed that more than 200 metabolic enzymes exist directly on human DNA. Many of these enzymes are commonly known to generate energy in mitochondria, but researchers have discovered that they reside on chromatin within the cell nucleus. This study shows that different cell types, tissues, and cancers each exhibit their own unique arrangement of metabolic enzymes within the nucleus. These enzymes interact with DNA in a pattern the researchers describe as a “nuclear metabolic fingerprint,” providing the first evidence that human cells may retain such a unique nuclear signature. Scientists still need to elucidate…

Areas frequently hit by severe storms also could face a more extreme hail threat, such as the Midwest, which was hit by powerful thunderstorms and deadly tornadoes last weekend. A new study published Monday in Atmospheric Science Letters is the first to link anthropogenic warming to hail size in a single thunderstorm. The study examined the May 3 storm that dumped hailstones ranging in size from marbles to golf balls across Paris and other parts of France, destroying or damaging property worth more than $350 million. The researchers compared real-time data from May 3 to similar weather patterns from previous…

Malignant gliomas have the highest mortality rate of all brain tumors, treatment options are limited, and survival rates are low. A new comprehensive review analyzes decades of global clinical data on the targeted radiation approach boron neutron capture therapy (BNCT). This study found a consistent survival benefit across multiple tumor types and treatment settings. By synthesizing evidence from accelerator- and reactor-based studies around the world, this study highlights the new clinical potential of BNCT and outlines key challenges for broader adoption. Malignant gliomas, including glioblastoma, are among the most aggressive and deadly brain tumors. Even with surgery, radiation therapy, and…

A large cross-sectional study of Japanese adults with type 2 diabetes found that alcohol consumption can affect dietary patterns and micronutrient intake differently by age and gender groups, with young men showing the most pronounced nutritional deficiencies. Association between alcoholic beverage consumption and micronutrient intake in type 2 diabetes outpatients: A cross-sectional analysis by gender and age (JDDM#). Image credit: Halfpoint / Shutterstock In a recent study published in the journal Clinical Nutrition ESPENresearchers investigated the association between alcohol intake and micronutrient intake in patients with type 2 diabetes (T2D). Alcohol intake can affect diet quality. Increased alcohol consumption is…
